World No.2 Andy Murray has outclassed Australian Sam Groth 6-0, 6-4, 6-1 to advance to the third round of the Australian Open.
The win means Murray remains undefeated in Tour-level matches against Australians.
He was in complete control from the outset, winning the first set in under half an hour, as he dropped just five games for the match.
Groth's usual big serve failed to trouble Murray, with the Brit serving nine aces compared to the Aussie's six.
The four-time Australian Open finalist looked in ominous form, hitting just 11 unforced errors for the match, as he aims to break his hoodoo at the first Grand Slam of the year.
Murray will next play No.32 seed Joao Sousa, who defeated Santiago Giraldo 6-3, 7-5, 3-6, 6-1 earlier on day four.
